Answer 1

Answer:

The answer to your question is 21 bikes and 6 trikes

Step-by-step explanation:

Data

27 seats

60 wheels

there are bikes and trikes

Process

1.- Remember that both bikes and trikes have only 1 seat, then there are 27 bikes and trikes.

2.- Bikes only have 2 wheels and trikes have 3 wheels.

3.- We know that there are in total 60 wheels, so let's guess

- There are 10 bikes that mean 20 wheels and 17 trikes, that means 51 wheels, total number of wheels = 17 + 51 = 71

- There are 15 bikes = 30 wheels and 12 trikes = 36 wheels

  Total number of wheels = 30 + 36 = 66

- There are 18 bikes = 36 wheels and 9 trikes = 27 wheels

 Total number of wheels = 36 + 27 = 63

- There are 21 bikes = 42 wheels and 6 trikes = 18 wheels

  Total number of wheels = 42 + 18 = 60 wheels

  DONE!!!
